[REF] website: merge BodyManager and WebsiteRoot

Following the new editor's merge at https://github.com/odoo/odoo/pull/29775,
'web_editor.BodyManager' stopped being used by the editor and the
related file was moved to website without being renamed or considered.

Hopefully, the editor replaced it by something else so the `BodyManager`
makes no sense on its own anymore. This commit merges its features
with the only other component which still used it: `WebsiteRoot`

See upcoming improvements at https://github.com/odoo/odoo/pull/29442
(related to task-1932066)

closes odoo/odoo#30740
